I'm a bit fan of the choice of music, nice pirate flair with a touch of rock. Good job.
The game was fun. It's a little bit tricky to hit the enemies, but if you made it it feels very well. Sometimes its quite impossible to hit somebody, while rotating and the enemy follows you. Would be nice if acceleration and decceleration would have more impact on that, or maybe I'm to bad.
If adding some funny power ups and skills this game could be a really nice horde survivor with another setting as the known games.
